Ok, well im look at getting rid of the 94 gt, and upgrading into a 1999 or 2001 cobra. Id love an 02-04, but couldnt afford one.

Anyway, my first question is, is there any major changes between the 1999, and the 2001,i know the 01 has 15 more horses, and that the 1999s didnt all have the horsepower that they were said to have. Was there any kind of recall for the 1999s,to fix that?

My next question is, what are the differences in the body from the 99-01 and the 02-04. I know the front bumper is, and im thinking the rear one is too. Anything else im missing? Can you put the 02-04 bumper on an 99-2001.

Finally, any input on them would be great. My parents owned a 99 cobra convert when i was 10, they bought it new. We didnt have it very long because of the top having a major leaking problem. Did anybody else ever have a problem with that, or anything I should know?

Thanks in advance.

as far as the 99 cobras r concerned....i know that a lot of them were recalled for the motors not putting out the correct amount of HP to the wheels. Basically ford just replaced the motors....if im not mistaken. I own a 99 cobra and let me tell you that the power is there but sometimes it does feel a bit slower than what it should be. Just giving ya a heads up.

As far as the body is concerned, in 03/04 the bumpers were changed. The sexier bumpers were put on. The 99 cobras just said mustang in the rear and then they changed it in 00 and it finally said cobra in the rear.

Ok, did anything else really change on the body besides the bumpers then?

After they rec'd the fix, I don't believe there was much difference.. not to sure.. but if you can afford a 01' Cobra which are in the high teens, why not look for a 03/04 Mach 1, they're faster.. and about the same $$

+1
My 04 Mach is a blast to drive and goes pretty damn good for a N/A car.I'm still a hugh fan of the 03-04 cobra's and i hope to have one someday soon.But seeing i just bought my 04 mach a few weeks back the cobra will have to wait.

What kind of power is a stock mach 1making? I know the 01 cobra is 320ish.

Well with the mods that i have on the Mustang dyno i'm putting down 264 rwhp and 330 at the crank.On the dynojet that would be 288 rwhp and 354at flywheel.I still need to get the car tuned.Oh yeah these times were based on stk mufflers with high flow cats.I now have flowmaster 40's and a offroad xpipe so i should maybe gain 1or 2 hp,lol.

+2 for the MACH 1 owners. I love the mach1's. I tried looking for one before I nabbed my cobra. They were a bit pricey everywhere I went though. On avg. i was finding em for like 22-25K. I was like FAK that. Don't they come 305 horse to the crank.

If you can get your hands on a mach 1 for a reasonable price then pic it up.

Holy crap there's a lot of inaccurate info in this thread....

There was no 02 Cobra in the US.

They were BOTH rated at 320hp. The 99s were recalled and most got "the fix".

My next question is, what are the differences in the body from the 99-01 and the 02-04. I know the front bumper is, and im thinking the rear one is too. Anything else im missing? Can you put the 02-04 bumper on an 99-2001.


The front bumper is identical. the 01s got smoked headlights and "Mustang" was changed to "Cobra" on the rear.

as far as the 99 cobras r concerned....i know that a lot of them were recalled for the motors not putting out the correct amount of HP to the wheels. Basically ford just replaced the motors....if im not mistaken. I own a 99 cobra and let me tell you that the power is there but sometimes it does feel a bit slower than what it should be. Just giving ya a heads up.

Not even remotely close. Are you sure you own a Cobra?:eek:

"The fix" included a ECU reflash, a ported intake and a new catback. Most dynoed around 250ish before and 270+ after. A "fixed" Cobra can be identified by a green or blue dot on the intake right behind the alternator.

I got mine used with 49k on it and it dynoed 272/304, bone ass stock.


As far as Cobra vs Mach, both are awesome cars, but I got a Cobra for the IRS and it feels much better to own one:D.

Well with the mods that i have on the Mustang dyno i'm putting down 264 rwhp and 330 at the crank.On the dynojet that would be 288 rwhp and 354at flywheel.I still need to get the car tuned.Oh yeah these times were based on stk mufflers with high flow cats.I now have flowmaster 40's and a offroad xpipe so i should maybe gain 1or 2 hp,lol.


354 TQ? I'd loooooooove to see that dyno sheet. Rather than call BS, I'll just say that's reeeeeeeeally hard to believe.

OK no need to jump down my throat about it or neone elses.All I know is that my boy had one and he got a new motor....don't ask me how, maybe he has some connects.

and yes I'm sure I have a cobra.....unless GT's come stock with 4V's now:D

I didn't mean to be a dick, but after cruising through some of these posts I blown away by MASSIVE levels of wrong info. I'm no expert, but I know what I'm talking about when I post. The poor guy is trying to make an educated decision on a several thousand dollar car, not a pair of shoes. Let's tighten it up around here....

Bygones....;)

why is it that people say the mach's are faster?

anyways back to the cobra i have a 01 putting 319 to the wheel and it is pretty damn fast. low end feels a lil sloppy, but i heard there low ends are for crap.[:@]

Because in the 1/4, everything equal they are. I'd love to see your mods list...

I wasnt saying it had 354 tq,what i said was thats what it should have for power at the flywheel based on the dyno jet times.

-strut stiffiners
-3.73's
-nitto 555 extreme's
-hawk hps brake pads(i think thats what they are called)
-internal antenna
-eibach drop 1.5'

there was a tune done with those parts

then he added custom 3.5' tail pipes from the 40's out and under drive pullies

He rigged the dyno. With those mods you're at 305, 310tops, including the pullies....

Power is like crack: Addicting. If someone can give you some, you want more and keep coming back. Any shop can make a dyno read whatever the hell they want. Or, as in 01snakes case, they can give a kindergardener a piece of paper and a box of Crayolas....

It's possible, but my shop knows I know enough to say BULL$HIT when I see it.My car was dynoed on a customer dyno day on aDynojet 224xLC. 50+ cars got strapped to the dyno that day. If you were a shop owner would you take the chance of pissing off that many Mustang owners? Nieither would I. My #s are dead smack inline with the few mods I have.

Your only realpower mods thereare the intake and midpipe. Your car would have dynoed bone stock in the 270s. Guaranteed. No freakin' way you would get 40 to 50hp from a filter and midpipe. Terminators don't even see those increases with those mods. You got stroked, bro. There's no other way around it....

mine did dyno 277rwhp stock

i forgot to add i have a diabloe tuner chip, bbk 65mm throttle body, and ported upper intake manifold

was urs tuned?

i am having trouble uploading this damn dyno sheet, on my friends comp we used for the fake dyno it was easy

I love my Cobra. The Machs are cool too, but there's something about a Cobra that turns heads. +1 for SVT.

Mine has not been tuned. I'm waiting for a new catted midpipe and gears first. I've seen cars with all your mods and longtubes barely break 310....

Terminators with intake, tune and midpipe will see approx a 50rwhp increase... (from 370ish to 420ish)... well most will atleast...

but as far as this 01' Cobra goes... still from your mods you won't pick up 40rwhp, the only reason the Terminators do is because of that little blower that sits on top of our motors.. kinda aplifies things... That manifold, throttle body, that's not doing much for you. Isn't your stock throttle body 65mm? Your Diablo chip, is that a dyno tune or a canned tune? I would say with your mods you're probably at around 300rwhp + or - a few...

The reason why dyno guys do that sometimes is because they make themselves look better on the tuning side, having you come to them for more things, and refer people to him because of his great tuning abilities.

the chip was for the tune with everything i have except the tailpipes and under drive pullies.

One of you is full of crap. It's either you or your shop.

lol. this is hilarious nither of us are full of crap.

think about it your car put 292rwhp (without exhaust)with out a tune. with a tune what do you think your gonna put?

i dont understand how you dont think it is possible.

i dont understand how you dont think it is possible.

It's not that I don't think it's possible, I KNOW it isn't possible. How many people do you need to hear it from?

what your saying is your car without exhaust or a tune is putting out 292 rwp add another 10-15 for an exhaust and an another 15 for an tune and your at about 320 and i have a ported intake. so why is that so hard tounderstand?

Alright, NOOB. This is how it works....

A midpipe will get you 5 to 8, a K&Nmaybe 3 to 5 and a tune might get 8 to 10. You're saying you have 319 BEFORE pullies? And I've got news for you, those pipes didn't do dick for you because all the exhaust restriction is in the manifolds and the midpipe.

My car baselined at 274 under perfect conditions.Another 18 between a good CAI and pullies is very realistic on a 4V. Two different types of gains, too. Reduction of parasitic losses and increased airflow. You're using ricer math, bro.....

My goal here was not to break you down. The goal was to help you get your **** straight so you don't get flamed by others who know how this stuff works. You obviously don't know what you're talking about, and that's okay; we all learn eventually.But you need to cut it out because we know what we're talking about around here....

Quit arguing with me and eithergo find a tuner that won't dick with you or at the very least educate yourself....

Well, just today I put down 465 at the wheels with my 01 GT with only a short shifter and K&N. The gears were even out of it. Just look!

http://i173.photobucket.com/albums/w43/caseychill/100_1040.jpg

I'm not saying you're lying.....but we have yet to see the sheet.....never the less, if you do have the sheet, just get it dyno'd by a 2nd REPUTIBLE shop and see if they match.

Simple way to prove your car made the power. Post a dyno sheet from the first shop then go to a second dyno (make sure its the same TYPE of dyno) and get another couple runs in. I will bet you don't see numbers that are even similar. Nobody believed that I made 420whp401wtqwith 15 degrees of timing and an 11.76 A/F. So when another shop had a dyno day I was glad to throw my car up on the dyno. It put down 418whp 406wtq (basic variance between runs and due to different conditions). Now I have 2 dyno sheets from different shops that show that my numbers aren't BS. Not saying you have to do it because you can believe whatever you want, but POISND U is just trying to explain that your numbers are not practical nor probable.

i have the dyno sheet uploaded on the comp. but i cant copy and paste it for some reason?

As I said before, it's not that we don't believe that's what the dyno said, it's that we KNOW it isn't possible....

i have the dyno sheet uploaded on the comp. but i cant copy and paste it for some reason?I'm not sure it's going to matter, 01.
You post a pic of the sheet, they'll say it's chopped
You post a vid of the dyno pull, they'll say (as they already have) that the dyno is rigged.
You post a vid of your car at 319 rwhp running, say, a 12.60-12.90 at 105-110and they'll say the video is faked. Or that it isn't your car.
You could snailmail each one of the non-believers a raised seal certified copy of your dyno sheet and they'll say that you paid someone off at the courthouse.

See where this is going? They know what they know and anything that is outside of that is patently false and they'll come up with a reason why.

I'll admit that 319 rwhp with your power adding mods (K&N, O/R X, flows - debatable -65mm TB, ported upper, custom tune) is a stretch. But in post # 29 poison said it'spossible but does say (correctly at that point of what he knew) that a mid-pipe and K&N ain't gonna getcha 42 rwhp.I'd just about go to the mats on that and say he's right - 42 rwhp with filter and mid-pipe/mufflers strains all kinds of credibility.

But that's NOT all you've had done. You tell them that the car dyno'd 277 rwhp stock. Nobody called you out on that since it's believable and about right. What they're saying is that top shelf numbers with your mods is probably 310 rwhp, so they just can't let go of that extra 9 hp that may have been found on the dyno, because of WHAT THEY KNOW, like in post 37, or more recently, the one above. For them, it's set in stone. I just don't like that kind of thinking, though.

I'll say that it's a stretch but not outlandish. Post a pic of the dyno sheet because with that power claim, it should be verified. And then move on. No matter what you do, there will always be some that do not believe.

First of all, I appreciate your attempt at fairness.

Second, I said I've seen cars with all his mods PLUS LONGTUBES barely hit 310.

Third is that no one has pointed out (until now) he stated that his K&N and midpipe got him to 319! Before pullies and catback, no less.

Finally, no one has pointed out that he apparently forgets what mods he has and only remembers after he gets asked to back it up. All of the sudden the dude says he has a tune, TB and a ported intake. I even let that go....

My point wasn't to originally call BS to HIM, but to his shop. He obviously isn't terribly knowledgeable about his car and I said that someone's yanking his chain. I may call him gullible, but I also gave him the benefit of the doubt. He starts pulling "forgotten" mods outta his butt, soyeah, I question the accuracy of my previous hypothesis and up the "BS flag" goes.

Like I said, someone's full of crap: either you or your shop. I used to think it might have been the shop. Now I'm not too sure....

thank you.yes as i said off the top of my head, i just got this car about 2 weeks ago and the guy had all this done.

i went thru the papers again and seen that he had a tune, chip, ported manifold, the throttle body i realised he must have had taken off cuz the one that is on the car says ford.

i have a quick problem i just realised when i drive my car hard always when i shift from 1st (around redline) to 2nd i will make a pop noise. i think it is a back fire. could this be to it being tuned to rich?

is this harmfull to my engine? i plan on getting cams within the next 1-2 months so i will have it re-tuned but in that time frame is anything potentially dangerous to my engine

Lol I feel bad for the OP. There were a significant number of changes from the '99 to '01 snake. Here's what I came up with:

The engine block was changed from the Teksid block to the Windsor Aluminum Plant or WAP block. The WAP block is regarded to be weaker than the previous Teksid block. Some 2001s received the Teksid, either from the factory or as a replacement motor
Newer revision cylinder heads.
Cobra-specific seats with a combination of leather and suede-like microfiber inserts - 1999 Cobras had normal Mustang seats.
A rear bumper that reads "COBRA", instead of "MUSTANG", as the 1999 Cobra had.
A rear badge on the trunklid was changed to say "SVT" instead of "SVT Cobra" as the 1999 Cobra had.
The option to order polished wheels from the factory.
The T-45 transmission in the 1999 model was replaced by the 3650 in the 2001 model.
The IRS halfshafts and differential were changed from 28 splines in 1999 to 31 splines in 2001.
The spoiler was redesigned.
The CD player was upgraded to a 6 disc unit.
The center console and trim were redesigned
The emergency brake was fitted with a 'boot' of leather to cover the hole in the console where it protrudes.
The headlights were changed to a tinted design.
The color of the odometer digits was slightly changed, and the color of the instrument cluster lighting was slightly changed as well.
Here's the source of the info.: http://en.wikipedia.org/wiki/Ford_Mustang_SVT_Cobra
I know Wikipedia isn't infallible, but this sounds pretty complete. I would say that if you can find a good deal on an '01 Cobra and you have the money, by all means, get it. However, when I was shopping around, the cheapest '01 I could find in my area was around $16k. The cheapest '99 I could find was around $12k... both cars had around 50k miles.

So umm yeah, Should i get the 01 cobra over the 99?Yeah, I'm thinking you should. ;)

i have a quick problem i just realised when i drive my car hard always when i shift from 1st (around redline) to 2nd i will make a pop noise. i think it is a back fire. could this be to it being tuned to rich?

is this harmfull to my engine? i plan on getting cams within the next 1-2 months so i will have it re-tuned but in that time frame is anything potentially dangerous to my engine

Sounds similar to a situation I dealt with on my 95GT. Every time I'd put that Horse through his paces and make a hard low shift (1-2 or 2-3), I'd get a pop. At first, like you, I thought it was backfire (actually kinda liked it). Turns out, it was driveline slop being taken up, lash in the tranny. So yours may not even be engine related.

But let's say it is, though. I don't think you're necessarily spoiling for trouble if you're getting a little mid-shift crackle and/or backfire. But just for good measure, have you had your A/F ratio checked?

it was driveline slop being taken up, lash in the tranny

^ what do you mean by that? is that bad?

thanx for the help

i was dynoed at 320 ft. lbs of torque when i bent my g/f over, then i started misfiring had to shut it down and went to sleep.

thanx for the helpLash is that fractional space between components (tranny, gears, valvetrain components, internal engine items like oil pump gears, distributor gears where applicable etc.) andthe like. A lot of times you'll hear cams advertised with "Lift and duration at fifty thousanths (.050) lash"- that's referring to thespace between the cam, the lifters, pushrods (where applicable), rocker arms and valves.

And we're talking space on almost amolecular level measured in thousanths of inches - the tolerances are very tight.Lubricants fill this space for the most part, but as an engine or driveline wears, that space widens. Most of the time, you'll never notice it - maybe the engine holds 40 psi of oil pressure when it used to hold 50, or in the case of "driveline slop," the shifter and/or clutch feels a little 'looser' than it used to, doesn't shift as tight, etc but you don't really notice the driveline lash overall. Until you bang on it. Then instead of those gaps gently and slowly closing up and working together to give you a smooth transition, they SLAM SHUT because you're wailing on it and BANG! it makes a noise. Sometimes a lot like a pop or a backfire.

Engine and driveline wear is a fact of life. You drive 'em, they'll wear out. But when your driveline lash (slop) gets to the point where it's making a noise on hard shifts, then replacement is on the horizon, because at that point, the tolerances are soout of specthat something is going to give way, and it's usually pretty violent and destructive.

Two schools of thought if you discover that your popping noise is in your driveline and not out of your tailpipe - drive it til it breaks, then replace it. The easier you drive it, the longer it will last. Dump the clutch and bang gears with slickson a regular basis, and you'll be replacing stuff in no time flat. No big revelation there. Might be a month, might be a year, but hardlynever - when they start whining, the end is near. Mine went very quickly from a pop to a shimmy to a lunk to dead. But I also drve the sh!t out of it! [sm=devilgrin.gif]

The other is to get out ahead of it so it doesn't leave you stranded somewhere (at the track, in themiddle of an intersection, orhanding an f-body its ass :D, etc) by having a reputable shop in your case check out your driveline components, identify the offender or offenders, and replace. The usual suspects in a case like this are gears and synchronizers in the tranny, output shaft, in some cases U-joints (although they break quickly once they start to go) and 3rd member gears/axles. If you want to check these things yourself, there are some shadetree methods you could use but the sure way to check is with a trained eye, experienceand proper equipment (dial calipers, etc.).

Good luck. Take it easy on those redline powershifts until you get this snockered! ;)

forgot to mention also when i rev it up to around red line and will let it drop 1000rpm's then rev it back up it makes the noise. so if i understand the slap correctly it must be my air fuel mixture is wrong

Yes, I would agree. But now you got a lesson in lash, right? If someone asks you what lash is, you can start off with "The fractional, almost molecular spaces between components" and take it from there. I think you ought to try it at a bar!! ;)

Get that A/F ratio checked

lol

ya I'm calling b.s. there no way you did that[&:]


Pat you might have a ford racing throttle bodie and thats why it says ford.

great now ur chimming in

lmao

is eric buying that car

and i know it says ford he took it off,but it was onlya 65mm same as stock one

Back to the OP...

I have an '01 Cobra 'vert, only mods are a KN CAI, a Steeda shifter and a Kirk roll bar. I've never had her dynoed, so I have no idea what she's really giving me. It's loads of fun, sounds awesome without making you deaf (ground noise in a 'vert can be very loud) and I even take it to the track. Best time was 13.82, not too shabby for a girl *wink*

The other day I got my doors blown off by a chick in an '03, but hey, it is what it is :)

So, definately do the '01 if you can't afford the '03.

did u get your doors blown off cause you were too busy staring?? Just wondering as a fellow female driver... I just wanna know what I am up against! LOL... ;)

Are the dyno sheets ever going to get posted?? I am a little curious as to which one was full of it... however... I do agree its a little hard to believe!!! :D

I've already talked to a buddy of his and he said the sheet says 319, but what was on the sheet was never in question....

Dyno's can say w/e they want.. the real use for them is to find out how much power you made between mods, and to use it as a tuning device, but they can be off, and read way off like I believe is happening in this case... If the dyno really is a 319 then there is probably something on the car he's not aware of.

It almost sounds like your clutch is slipping a little bit too...
